The Storm Stag Beetle is a Storm-attributeBox Weapon that covers its jaw with Flames that possess a Disintegration effect. Baishana's Storm Stag Beetles were remodeled from the one designed by Lorenzini and possess an agility that is not present in the original. However, Box Weapons that undergo this kind of artificial remodeling often present some sort of fatal weakness, thus being called "Unbalanced Boxes".

Baishana has eight of these secondary Box Animals and uses their number, speed, and flight abilities to confuse and overwhelm his opponents.
